Increasing evidence supporting the role of immune checkpoint blockade in cancer management has been bolstered by recent reports demonstrating significant and durable clinical responses across multiple tumour types, including metastatic urothelial carcinoma (mUC).

Circulating tumor cell (CTC)-filtration methods capture high numbers of CTCs in non-small-cell lung cancer (NSCLC) and metastatic prostate cancer (mPCa) patients, and hold promise as a non-invasive technique for treatment selection and disease monitoring.

Organ-confined muscle-invasive bladder cancer (MIBC) is treated with cystectomy or bladder preservation techniques, including radiotherapy. There are currently no biomarkers to inform management decisions and aid patient choice.

Treatment of metastatic clear cell renal cancer (mccRCC) has seen substantial progress over the last 20 years, with many regulatory approvals since 2006 culminating in a substantial increase to overall survival (OS).

Tumor heterogeneity strongly affects the molecular mechanisms driving resistance to hormonal therapies in castration-resistant prostate cancer. Since the current use of available treatments can be optimized on the basis of the molecular profile of tumor, the present review focuses on genetic biomarkers in prostate cancer and their application to a personalized treatment.

BACKGROUND - Axitinib is a potent inhibitor of the vascular endothelial growth factor (VEGF) receptor family with clinical activity in patients with metastatic renal cell carcinoma (mRCC). Given this biochemical potency, the clinical activity of subsequent treatment with targeted therapies in patients progressing on axitinib is of interest.

On the grounds that miRNAs present in the blood of prostate cancer (PCa) patients are released in the growth medium by PCa cells, it is conceivable that PCa cells resistant to docetaxel (DCT) (DCT(R)) will release miRNAs that may be found in PCa patients under DCT therapy if resistant PCa cells appear.

Detection of Circulating Tumor Cells (CTCs) in peripheral blood can serve as a "liquid biopsy" approach and as a source of valuable tumor markers. CTCs are rare, and thus their detection, enumeration and molecular characterization are very challenging.
